Description

Technical Field

[0001] The utility model relates to the field of woven bag processing equipment, and particularly relates to an automatic inner bag nesting mechanism during the processing of multifunctional woven bags. Background Art

[0002] When the bag body needs to be filled with relatively fine powder and odoriferous materials, an inner bag needs to be nested inside the woven bag. Currently, the inner bag nesting is mainly done by manually nesting the inner bag into the woven bag. The specific method of nesting the inner bag is to put the bag body on a U-shaped rod, and then put the woven bag body on the U-shaped rod to complete the nesting of the inner bag. Then, the staff takes the inner bag and the woven bag off the U-shaped rod. In this way, the efficiency of nesting the inner bag by the staff is relatively low, and the corresponding labor cost is relatively high.

[0003] Generally, after nesting the inner bag, the bag body needs to be hemmed. Currently, after the inner bag and the bag body are nested, the bag mouth of the inner bag and the bag mouth of the bag body are in a separated state. When hemming, the staff still needs to arrange the bag body (make the bag mouth of the inner bag fit the bag mouth of the bag body), which is convenient for subsequent hemming. However, after the above-mentioned inner bag and bag body are nested, the bag mouth still needs to be arranged, which is not suitable for automatic hemming. Summary of the Invention

[0019] As Figures 1-4 shown, an automatic inner bag nesting mechanism for processing a multifunctional woven bag includes an inner bag supply mechanism 1, a bag body opening mechanism 15, an inner bag nesting mechanism 22 and a gluing mechanism 28. An inner bag nesting mechanism 22 is arranged between the inner bag supply mechanism 1 and the bag body opening mechanism 15, and a gluing mechanism 28 for brushing glue on the inner bag mouth is arranged on one side of the inner bag nesting mechanism 22;

[0020] The inner bag nesting mechanism 22 includes a rotating wheel 23, a U-shaped rod 24 and a push block 25. A horizontal rotating wheel 23 is installed on the ground through a bearing and a bearing seat. The rotating wheel 23 is driven by a stepper motor, that is, the shell of the stepper motor is installed on the bearing seat through bolts, and the output shaft of the stepper motor is fixed to the rotating wheel 23. A plurality of U-shaped rods 24 arranged at equal intervals are arranged on the outer periphery of the rotating wheel 23. The U-shaped rod 24 is a hollow rod. A guide rod 26 is inserted into the hollow part of the U-shaped rod 24. The guide rod 26 is a multi-faceted rod to prevent the guide rod 26 and the U-shaped rod 24 from rotating. The other end of the guide rod 26 is installed on the rotating wheel 23 by welding. A spring is sleeved on the guide rod 26. The two ends of the spring are separated by welding. The U-shaped rod 24 is fixed on the rotating wheel 23, and the U-shaped rod is pulled toward the rotating wheel 23 by a spring. A push block 25 extending outward is installed at the root of each U-shaped rod 24 by welding. Four groups of push linear motors 27 are installed on the ground on the front and rear sides of the rotating wheel 23. Two groups of push linear motors 27 are arranged on the front and rear sides of the rotating wheel 23. The mover of the push linear motor 27 is against the push block 25. When the mover of the linear motor moves outward, the mover pushes the push block 25 to move outward, so that the U-shaped rod 24 is lifted outward, and the U-shaped rod 24 is pushed outward by the push linear motor 27; the inner bag is put on the U-shaped rod through the outward lifting of the U-shaped rod 24, and the inner bag on the U-shaped rod is extended into the bag body.

[0021] The bag body opening mechanism 15 includes a placement flat plate 16, lifting rods 17 and negative pressure nozzles 19. Among them, the placement flat plate 16 is installed on the ground on the right side of the rotating wheel 23 through a column. Above the placement flat plate 16, two longitudinally arranged lifting rods 17 are provided side by side. The bag body is placed on the conveying flat plate 16. On the top surface of the conveying flat plate 16, two longitudinally arranged long strip-shaped grooves are opened. In each groove, a conveyor belt driven by a motor is embedded. A plurality of countersunk holes are opened on the outer wall of the conveyor belt, and a negative pressure head is embedded in each countersunk hole. The negative pressure head is flush with the top surface of the conveying flat plate 16, so as to realize the conveyance of the bag body on the conveying flat plate 16. A gantry is installed above the conveying flat plate 16 by means of bolt fastening. A lifting cylinder 18 is arranged between the lifting rod 17 and the placement flat plate 16, that is, the cylinder body of the lifting cylinder 18 is installed on the gantry by bolts, and the piston rod of the lifting cylinder 18 is installed on the lifting rod 17 by means of bolt fastening. The lifting of the lifting rod 17 is realized by the telescopic movement of the lifting cylinder 18. A countersunk hole is opened at the bottom of each lifting rod 17, and a negative pressure nozzle 19 is embedded in the countersunk hole at the bottom of the lifting rod 17. A negative pressure nozzle 19 is installed on the placement flat plate 16 opposite to the negative pressure nozzle 19 on the lifting rod 17, that is, a countersunk hole is also opened on the placement flat plate 16 opposite to the upper and lower positions of the lifting rod 17, and a negative pressure nozzle 19 is also embedded in the countersunk hole. The negative pressure nozzle 19 is connected and communicated with a negative pressure pump through a pipeline. The negative pressure nozzle 19 forms a negative pressure through the negative pressure pump, and the negative pressure nozzle 19 adsorbs the outer wall of the bag body. When the lifting rod 17 rises, the bag opening of the bag body opens, which is convenient for the U-shaped rod to embed the inner bag into the bag body;

[0022] The gluing mechanism 28 includes a mounting frame 29, a glue spraying head 30 and a telescopic assembly 31. A groove body is opened on the mounting frame 29, and the bag body extends into the groove body. The glue spraying head 30 is arranged on the inner side of the groove body of the mounting frame 29. A telescopic assembly 31 is arranged on the mounting frame 29. The telescopic movement of the mounting frame 29 is realized through the telescopic assembly 31, so that the bag body extends into the groove body of the mounting frame 29;

[0023] The gluing mechanism 28 includes a mounting frame 29, a glue spraying head 30 and a telescopic component 31. The mounting frame 29 is installed on the ground on the side of the rotating wheel 23. A groove is formed on the mounting frame 29, so that the mounting frame 29 forms a U shape. The outer side of the inner bag mouth extends into the groove. The glue spraying head 30 is installed on the inner side of the groove of the mounting frame 29 by means of bolt fastening. The outer side of the inner bag mouth is glued through the glue spraying head 30. The telescopic component 31 (the telescopic component 31 includes a straight rod, a telescopic cylinder and a cylinder) is installed on the mounting frame 29 by welding. A column is installed on the ground by bolts. A plurality of telescopic cylinders are installed side by side on the column by bolts. The straight rod passes through the telescopic cylinder and slides back and forth along the telescopic cylinder. A cylinder is installed between the rear end of the straight rod and the column by bolts. The telescopic movement of the mounting frame 29 is realized through the telescopic component 31, so that the bag body extends into the groove of the mounting frame 29. When working, when the U-shaped rod with the inner bag rotates to directly above the rotating wheel 23 and the U-shaped rod is vertically arranged, the mounting frame 29 is lifted and moved forward by the cylinder, so that the bag mouth extends into the groove of the mounting frame 29. The glue spraying head 30 sprays glue onto the outer wall of the inner bag mouth. The glue spraying head 30 is connected to a box for placing glue through a pipeline. A pump body is installed on the pipeline through a threaded joint. When the inner bag extends into the bag body, the inner bag and the bag body are pressed together by pressing down the lifting rod, so that the outer wall of the inner bag mouth and the inner wall of the bag body mouth are bonded by glue, which is convenient for subsequent hemming.

[0024] The guide rod 26 is a multi-faceted rod. The top of the U-shaped rod 24 is disconnected to form a notch. A pressing block 20 is installed at the bottom of the lifting rod 17 and near the middle. The pressing block 20 corresponds to the notch of the U-shaped rod 24. A groove for the pressing block 20 to be embedded is formed at the bottom of the lifting rod 17. The pressing block 20 is embedded in the groove. An elastic telescopic component 21 is arranged between the pressing block 20 and the groove. The elastic telescopic component 21 is a spring. The outer wall of the pressing block 20 fits with the inner wall of the groove. In this way, the pressing block 20 rises and falls along the inner wall of the groove. The pressing block 20 is ejected from the lifting rod 17 through the elastic telescopic component 21. When working, the U-shaped rod 24 extends into the bag body, the lifting rod 17 descends, and the lifting rod 17 does not press on the bag body. The pressing block 20 on the lifting rod 17 presses on the bag body. The U-shaped rod 24 quickly retracts. Since the inner bag is pressed by the pressing block 20, the inner bag will not move with the U-shaped rod. After the U-shaped rod exits, the lifting rod 17 continues to press down and presses on the bag body. The gluing position on the inner bag corresponds to the upper and lower positions of the left lifting rod 17. After pressing is completed, the lifting rod 17 rises and the bag body is conveyed away.

A lifting negative pressure suction head 14 is arranged above the right end of the conveyor belt 13. A plate is arranged at the top of the right end of the conveyor belt 13. A plurality of negative pressure suction heads are fixed to the bottom of the plate by bolting. Cylinders are installed between both ends of the plate and the top of the flat plate 12 by bolting. The lifting of the plate is realized through the cylinders. In this way, the bag mouth of the inner bag is opened by the lifting of the plate, which is convenient for the U-shaped rod to extend into the inner bag. The negative pressure suction heads 14 on the plate of the conveyor belt 13 are connected and communicated with a negative pressure pump through a pipeline. Among them, a negative pressure cavity with an open top is installed below the upper belt of the conveyor belt 13.
